353.14=3.14x2

Solution for 353.14=3.14x2 equation:

353.14=3.14x^2

We move all terms to the left:

353.14-(3.14x^2)=0

We get rid of parentheses

-3.14x^2+353.14=0

a = -3.14; b = 0; c = +353.14;
Δ = b2-4ac
Δ = 02-4·(-3.14)·353.14
Δ = 4435.4384
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{4435.4384}}{2*-3.14}=\frac{0-\sqrt{4435.4384}}{-6.28}
=-\frac{\sqrt{}}{-6.28}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{4435.4384}}{2*-3.14}=\frac{0+\sqrt{4435.4384}}{-6.28}
=\frac{\sqrt{}}{-6.28}
